To all whom it may concern:

Be it known that T, LEONARD R. STEEL, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Vacuum-Insulated Oyster- Gans, of which the followingis a specification.

This invention relates to oyster cans.

One object of the invention is to provide a refrigerating can which will include an inner vessel and an outer vessel, and a cover fitted to the inner vessel and provided with a tray portion which is concealed by the cover and adapted to be viewed therethrough and to contain a sample of the contents of the inner vessel.

Another object of the invention is to construct the outer and inner vessels respectively so as to prevent the latter from moving laterally in the former.

In the drawings, forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views: Figure 1 is a side elevation of the can showing the cover in section. Fig. 2 is a vertical section through the can. Fig. 3 is a perspective view of the support. Fig. 4 is a perspective view of the companion parts of the display tray.

The can comprises an outer vessel which includes the inner walls 16, the outer walls 16 and the bottom members 5 and 14. The member 5 is connected, as shown, with the outer walls 16. The bottom 14 is connected with the inner walls 16, and as illustrated,

the said body is depressed to, provide the depending centrally disposed portion 15. The lower reinforclng band 7 is secured to the walls 16 and it extends below-the plane of the bottom 5 to protect the latter in transit of the can. The walls 16' are flared upwardly and inwardly and secured to the inner walls 16. Beneath the flared portion, the walls 16 are stamped to provide an annular reinforcing bead 8 against which the lower edge of the cover 32 is adapted to engage, as shown in Fig. 2- of the drawings. The cover comprises the inner and outer spaced walls 34 and an intermediate reinforcing element 35 of non-heat conducting material. The flange 33 of the cover is flared interiorly to correspond with the flared portion of the walls 16., A packing washer 17 embraces the upper end of the Specification of Letters Patent.

outer vessel and it is adapted to be embraced by the inner walls of the cover 32 so as to effect a perfect air tight connection between the cover and said outer vessel. The cover is provided with an opening 36, whereby air may be exhausted from the space between the walls of the cover. This opening may be closed by the plug 37.

A reinforcing element 19 of non heat conducting materlal is interposed between the walls 16 and 16 of the outer vessel. A perdrawn from the space between the walls 16 and 16' and the space 12. These openings may be sealed by the plugs 23.

The inner vessel 24 is provided on its bottom 25 with a centrall located depending reduced portion 26 which is adapted to be extended into the portion 15 of the outer vessel. The walls of the inner vessel 24 are spaced from the walls 16 of the outer vessel so as to form an intervening refrigerating chamber in which a refrigerant such as ice may be placed. A member 39 is fitted to the upper end of the inner vessel 24 and it is provided with an upwardly extending flange 39. The upper end of the vessel 24 is preferably provided with a flange 27 which is adapted to be embraced by the flange 38 on the member 39. A display tray for containing a sample. of the contents of the vessel 24, is shown at 41. This tray is adapted to fit within the member 39 and it is provided with an outwardly extending annular flange 40 which is adapted to rest on the flange 39 hereinbefore described. A cover 41 of transparent material is provided for the combined purposes of closing the vessel 24 and display tray. The cover 41 carries the flange 38. which embraces the flange 40 on the display tray and the flange 39 on the member 39. The cover 41 is spaced from the cover of the outer vessel so that the cold air in the refrigerating chambe permitted to circulate freely around and above the display tray.

A drain pipe 29 extends through the outer vessel and it opens into the space defined by the portion 15 of the inner wall 16. This drain ipe may be closed by a plug- 30 the latter mg preferably carried by a c ain 31 which is secured exteriorly to the outer vessel.

I claim A refrigerator com rising an outer vessel having double wa ls, a port located between the we Is and the bottoms thereof and including spaced inner and outer flanges, a reinforcm element interposed between the walls 0 said vessel and erforated suphaving central portion'at its bottom extende into the inner flange of said support and directly against the bottom of said inner wall, the bottom of said inner wall being also extended into the inner flan e of the support, and a rece tacle removabFy mo'unted in the vessel an having its bottom rovided with a reduced portion extending into the central depending portion of the inner wall.

In testimon whereof I aflix my signature in presence 0 two witnesses.
